Vikings promote OT Brown to the active roster; put OG Herrera on IR

The Vikings have added OT Patrick Brown to the active roster and placed OG Anthony Herrera on injured reserve.

Herrera tore an ACL in his left knee in the Vikings 31-3 loss to the Packers on Sunday. The seventh-year veteran started every game this season at right guard for Minnesota. Brown is a first-year offensive tackle who was promoted from the practice squad.
